<a name="gst-plugins-good-plugins-qtmux.description"></a><h2>Description</h2>
<p>This element merges streams (audio and video) into QuickTime(.mov) files.</p>
<p>The following background intends to explain why various similar muxers
are present in this plugin.</p>
<p>The <a class="ulink" href="http://www.apple.com/quicktime/resources/qtfileformat.pdf" target="_top">
QuickTime file format specification</a> served as basis for the MP4 file
format specification (mp4mux), and as such the QuickTime file structure is
nearly identical to the so-called ISO Base Media file format defined in
ISO 14496-12 (except for some media specific parts).
In turn, the latter ISO Base Media format was further specialized as a
Motion JPEG-2000 file format in ISO 15444-3 (mj2mux)
and in various 3GPP(2) specs (gppmux).
The fragmented file features defined (only) in ISO Base Media are used by
ISMV files making up (a.o.) Smooth Streaming (ismlmux).</p>
<p>A few properties (<a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--movie-timescale" title="The “movie-timescale” property"><span class="type">“movie-timescale”</span></a>, <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--trak-timescale" title="The “trak-timescale” property"><span class="type">“trak-timescale”</span></a>,
<span class="type">“trak-timescale”</span>) allow adjusting some technical parameters,
which might be useful in (rare) cases to resolve compatibility issues in
some situations.</p>
<p>Some other properties influence the result more fundamentally.
A typical mov/mp4 file's metadata (aka moov) is located at the end of the
file, somewhat contrary to this usually being called "the header".
However, a <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--faststart" title="The “faststart” property"><span class="type">“faststart”</span></a> file will (with some effort) arrange this to
be located near start of the file, which then allows it e.g. to be played
while downloading. Alternatively, rather than having one chunk of metadata at
start (or end), there can be some metadata at start and most of the other
data can be spread out into fragments of <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--fragment-duration" title="The “fragment-duration” property"><span class="type">“fragment-duration”</span></a>.
If such fragmented layout is intended for streaming purposes, then
<a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux--streamable" title="The “streamable” property"><span class="type">“streamable”</span></a> allows foregoing to add index metadata (at the end of
file).</p>
<p>When the maximum duration to be recorded can be known in advance, <a class="link" href="gst-plugins-good-plugins-qtmux.html#GstQTMux"><span class="type">GstQTMux</span></a>
also supports a 'Robust Muxing' mode. In robust muxing mode,  space for the
headers are reserved at the start of muxing, and rewritten at a configurable
interval, so that the output file is always playable, even if the recording
is interrupted uncleanly by a crash. Robust muxing mode requires a seekable
output, such as filesink, because it needs to rewrite the start of the file.</p>
<p>To enable robust muxing mode, set the <span class="type">“reserved-moov-update-period”</span>
and <span class="type">“reserved-max-duration”</span> property. Also present is the
<span class="type">“reserved-bytes-per-sec”</span> property, which can be increased if
for some reason the default is not large enough and the initial reserved
space for headers is too small. Applications can monitor the
<span class="type">“reserved-duration-remaining”</span> property to see how close to full
the reserved space is becoming.</p>
<p>Applications that wish to be able to use/edit a file while it is being
written to by live content, can use the "Robust Prefill Muxing" mode. That
mode is a variant of the "Robust Muxing" mode in that it will pre-allocate a
completely valid header from the start for all tracks (i.e. it appears as
though the file is "reserved-max-duration" long with all samples
present). This mode can be enabled by setting the
<span class="type">“reserved-moov-update-period”</span> and <span class="type">“reserved-prefill”</span>
properties. Note that this mode is only possible with input streams that have
a fixed sample size (such as raw audio and Prores Video) and that don't
have reordered samples.</p>
